Abstract
There is described an ink wiping system (100) for an intaglio printing press comprising a wiping tank (101) and a rotatable wiping roller assembly (102) positioned on and partly located in the wiping tank (101) to wipe excess ink from the surface of a rotatable intaglio printing cylinder (80) of the intaglio printing press. The ink wiping system (100) comprises a supporting mechanism (200) coupled to the wiping roller assembly (102) and designed to move the wiping roller assembly (102) between a working position where the wiping roller assembly (102) is positioned on and partly located in the wiping tank (101) for cooperation with the intaglio printing cylinder (80) and a maintenance position where the wiping roller assembly (102) is moved out of the wiping tank (101) and away from the intaglio printing cylinder (80). Preferably, the wiping roller assembly (102) comprises a rotatable hollow cylindrical body (110) having an outer surface (110a) positioned to wipe the surface of the intaglio printing cylinder (80).
